1) Alan Williams was found strangled to death in his apartment. The building's janitor, who was well-known to Williams, is accused of the murder on the theory that he had easy access to Williams's apartment. On the day that Williams was killed he had a phone conversation with a friend of his, Bruce Bender. Williams said to Bender, "I've got to hang up now. Somebody's just come in and he looks really upset. I don't know who he is, but he's got a crazy look on his face." Can the janitor have Bender give testimony quoting Williams
